Polymer additive identification and analysis. Showcase

Intertek's laboratory in Reinach (BL) offers standardized and R&D support services for the chemical identification of polymer additives in various plastic materials.

Service highlight

Usually the polymer is extracted using an appropriate solvent. The selection of the correct solvent for a particular polymer is essential for the successful extraction of polymer additives. The polymer extract is then analysed by LC-MS and GC-MS.

Polymer additives have different chemical and physical properties. LC-MS and GC-MS are complementary analytical techniques, their combined use maximises the chance of a successful analysis. LC-MS is better for high molecular weight and more polar additives. GC-MS is better for low molecular weight and less polar additives.

Intertek offers on-line pyrolysis-GC-MS of polymer chips as a quick low cost procedure to get preliminary data on polymer additives. This technique does not have the comprehensive scope of the solvent extraction-LC-MS/GC-MS procedure.
